Original cytotoxic bisindolealkaloids with a 1,2,3,4-tetrahydroquinoline bridge were synthesized by reductive amination with various anilines. The most cytotoxic compounds display a high and dose-dependent cell cycle effect with accumulation in the G1 phase. Influence of substitution of the starting aniline on the reaction and on cytotoxicity of produced dimers was pointed out.

catalytic hydrogenation of nitroarenes usinghydrogen gas as reducing agent to form substituted aniline derivates is an important reaction in industry and academic research. Here, we report on the nitroarene hydrogenation capability of a nanostructured nickel catalyst synthesized from a nickel salen complex and a commercially available porous silica support. Our catalyst allows the selective hydrogenation
For the purpose of developing new antiseptics, we searched for compounds having high biocidal activity covering both gram-positive and gram-negative bacteria. Accordingly, we designed 1,5-disubstituted biguanides and synthesized them using two alternative efficient reaction schemes. The bactericidal activity of these biguanides was assayed by the micro titration plate method. Among the biguanides synthesized, 3,4-dichlorobenzyl derivatives were found to exhibit particularly high bactericidal activity. Ultimately, compound 11 was chosen as a candidate novel antiseptic, which is currently under continued. evaluation. (C) 1997 Elsevier Science Ltd.
